Thread.sleep in loop warning

[Stefano Gargiulo]

Due to the new warning in 6.9 i ask you for confirmation if a loop of
this kind can have problems (i think no, i think the warning is just to
avoid typo in plain java code) :

while (!dests.isEmpty()) {
for (Thread tr : haircuttingSMTPs) {
if (!tr.isAlive()) {
haircuttingSMTPs.remove(tr);
if (dests.isEmpty()) {
break;
}
String dest = dests.remove(0);
haircuttingSMTPs.add(0, new Thread(new
DetachedMailer(message, dest)));
haircuttingSMTPs.firstElement().start();
break; //vector changed redo main while check.
}
try {
Thread.sleep(50); //sleep to give cpu to real
threads, this is just a controller
} catch (InterruptedException ex) {

Logger.getLogger(MassMailerThread.class.getName()).log(Level.SEVERE,
null, ex);
}
}
}
